Specification of Letters Patent.

Patented Dec. 19, 1916.

. Application filed September 28, 1916. Serial No. 122,711.

To all whom it may concern Be it known that I, DAVID L. Born, a citizenof the United States, residing at Solomon, in the county of Dickinsonand State of Kansas, have invented a new and useful Wrench, of which thefollowing is a specification.

The present invention appertains to wrenches, and aims to provide anovel and improved quick adjustable wrench, whereby the jaws can beadjusted relative to one another quickly to properly fit the nut orother object, and whereby when the jaws are adjusted to the desiredposition, they can be held efiectively in position without danger ofloosening.

It is also within the scope of the invention to provide a wrenchembodying a unique assemblage of the component elements, whereby thewrench is not only comparatively simple, compact and inexpensive inconstruction, but is also thoroughly practi- I cal, convenient andeflicient in use.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a side elevation, of the improved wrench, with the jaws locked.Fig. 2 is a fragmental section of the wrench, illustrating the movablejaw released so that it can be moved either toward or away from thestationary or fixed jaw. Figs. 3 and l are cross sectional details takenon the lines 3-3 and H, respectively, of Fig. 1.

In carrying out the invention, there is employed a stock 1, preferablyformed from a bar of suitable metal, and provided adjacent one end witha suitable handle 2. The other end of the stock 1 is provided with anangularly extending stationary or fixed jaw, which embodies an angularlyextending portion 3 projecting from the outer end of the stock 1, and apair of blocks 4 disposed upon opposite sides of the portion 3. AU-shaped yoke 5 has its limbs overlapping the remote or opposite sidesof the blocks 4:, and passes around the outer end of the stock 1, thebend or intermediate portion of the yoke 5 being spaced from the stockand serving as a guide for the movable jaw, as will hereinafter morefully appear. The parts, 3, a and 5 are preferably secured together bymeans of rivets 6, although it is to be understood that said parts maybe assembled in any other suitable manner, so that they are rigid withone another. That edge of the stock 1 which projects in the samedirection as the portion 3, is provided with a longitudinal series ofnotches or teeth 7 for holding the movable jaw 8 at various adjustedpositions.

The movable jaw 8 projects in the same direction as the stationary jaw,and is carried by a pair of parallel integral bars or strips 9 whichoverlap the opposite sides of the stock 1. The jaw 8 is carried by theouter ends of the bars 9 and project angularly therefrom, the bars 9normally being in alinement with the stock 1, so that the jaws projectin the same direction parallel with one another. The bars 9 passslidably between the stock 1 and yoke or guide 5,whereby the bars 9 areheld assembled with the stock, which enables the bars 9 to be swungslightly relative to the stock and stationary jaw, as illustrated inFig. 2, which allows the movable jaw to be slid longitudinally.

The inner ends of the bars or strips 9 are connected by a U-shaped yoke10 which projects in the same direction as the yoke 5, so that its bendpasses around that edge of the stock 1 opposite the edge having theteeth or notches 7 The yoke 10 securely fastens the inner ends of thebar 9 together, to brace them, and the opposite edges of the bars 9 areconnected adjacent their inner ends by cross members or teeth 11 whichare interengageable with the teeth or notches 7 of the stock, when thebars 9 are swung into alinement with the stock 1, as illustrated inFig. 1. The bend of the yoke 10 is spaced sufficiently from the stock,to allow the bars 9 to swing to the position illustrated in Fig. 2,whereby the teeth 11 are disengaged from the teeth 7 which permits thebars 9 to be slid longitudinally, for adjusting the jaw 8 either towardor away from the stationary jaw. The yoke 10 also serves as a supportfor a leaf spring 12, which has its butt end riveted to the bend of saidyoke, and the free end of the leaf spring 10 bears against that edge ofthe stockl opposite the teeth 7, to

the teeth 7 for holding the jaws locked relative to one another.

' In using the wrench, the yoke 10 can be readily pressed by the thumbor finger toward the stock 1, which releases the movable jaw, so that itcan be adjusted to the desired position quickly, and when the yoke 10 isreleased, the bars 9 will be swung into alinement with the stock 1, tolock the movable jaw in its adjusted position.

, The jaws may be toothed to enable'them to grip a pipe or othercylindrical object,

so that the pipe can be used as a pipewrench,

or the jaws may be left plain when the device is used as a nut wrench. 7

Attention is directed to the fact that when the bars 9 are swung torelease the movable jaw, the movable jaw is swung away from i thestationary jaw, so as to immediately release the nut or other object.

Having thus described the invention, what is claimed as new is:

1. A wrench embodying a stock having an angularly extending jaw at itsouter end, that edge of the stock which projects in the same directionas said jaw having a longitudinal series of teeth, a bar overlapping oneside of said stock and having an angularly extending jaw at its outerend cooperable with the aforesaid jaw, said bar having teethinterengageable with the aforesaid teeth, the stock having means at itsouter end for guiding said bar, and spring means between said bar andstock tending to move said teeth into engagement.

2. A wrench embodyingv a stock havingan angularly extending jaw at itsouter end, that edge of the stock which projects in the same directionas said jaw having a longi tudinal series of t-eth, a bar overlappingone side of said stock and having an angularly extending jaw at itsouter end cooperable with the aforesaid ja'w, said bar having teethinterengageable with the aforesaid teeth, the stock having means at itsouter end for guiding said bar, a member carried by the inner endof'sai'd'bar, and a spring carried by said member and'bearing againstthat edge of the stock opposite the V teeth and tending to move theteeth into ends coope able with the aforesaid aw, said bars having teethat their inner ends engageable withthe'aforesald teeth, sa d aw havln 'aguide at its outer end forguiding said bars, a yoke attached to theinner ends of said bars, and a spring carried by said yoke and bearingagainst the edge of the stock opposite said teeth to move the teeth 1 ofthe bars into en a ement with the teeth V b b V V of the stock. V -l-. Awrench embodying a stock having an angularly 'extending jaw at its outerend and a longitudinal series of teeth projecting 1n the same directionas said aw, a U-shaped yoke attached to said jaw and having its bendsurrounding the outer end of said stock, a pair of bars fittingslidably' between opposite sides of said" stock and said yoke and havingan angularly extendingjaw at their outer ends cooperable with-theaforesaid jaw, said bars having teeth at their innerends interengageablewith the aforesaid teeth when the bars and stock are swung intoalinement, a U-shaped yoke attached to the inner ends of said bars andpro ecting in the same direction as the aforesaid yoke,

and a spring attached to the second mentioned yoke and bearing slidablyagainst that edge of the'stock opposite the teeth thereof. 1

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in thepresence of two Witnesses.
